To all wi'wm/ it 721a concern.-

Bc'it known that I, ETHAN I. Dorms-a citizen ot the United States,residing at Pullman, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in BolsterConstructionsiorCars, of Which the following is a specification This inventionrelates to the construction of bolsters for cars, and although it isshown and described in connection with a car-body -2o anchors passingbeneath the outer having asloping floor or bottom and although it sespecially adapted to such use obviously it may be employed in any typeof car.

The invention involves several novel ieai turcs, among which may bementioned the use of an'inte ral strut and combined spacer or fillet forthe center sills in combination with one or more transverse tensionrodssocured at their outer ends to angle-caps or lower ends of thebody-bolster and side sills and resting on the combined strut andspacer. These tension-rods in my structure replace the usualtension-plate and have the advantages over the latter that easilyremoved or putin place as desired withoutcutting a single rivet, thatthey'are cheaper than the customary plate, and that they are arranged toperform their Function 0 more advantageously, since they extend over alonger span than the tension-plates do. ,As an additional feature .l:provide a bellied plate extending longitudinally. of thebolster, rivetedto the above-mentioned strut and secured to the bottom of the car-bodyby means 01 rivets and an angle-bar running along its upper edge. Thisplate acts, as will be obvious to those skilled. in the art, as a strutor support for the bottom of the car-body. Where such a strut is used ina car having a body with a sloping bottom, the angle-bar securing thesame to the bottom has its ilan es at an 'angle to correspond to theinclinatimi oi the body.

In the accompanying drawings, which form a part of the specification,.l. have illustrated one embodiment of my invention.

Figure 1 is a side elevation oi a portion ol a hopper car embodying myinvention. Fig. '2 is a longitudinalvertical section on the line 2- 2of- Fig. 3, and Fig. 3 is a transverse section on the line 3 3 of Fig.1.

they can be quickly and l i l l l f if I having integral lu The centersills comprise spaced channelbean's 10 1 0 with their flanges extendingontwardly, the sills being held apart, yet joined together, by spacer11, which includes arectangular lran e oi the form shown in Fig. 3, thewels oi the sills lzeingriveted to the spacer. Integral with. thisspacer are outstanding llangcs 12 12, overlapping the upper llanges olthe center sills, to which they are riveted, integral with which flangesare struts 13 13,

o 14 l l, each pair of struts being spaced apart, as shown in I ig. 2.Bodybolster hean'rs 15 are attached to the center sills by means ofangle-platcs l6 and to the angle side sills 17 and side stakes lb byanglehars i9. (.omprcssion angle-bars 20 are riveted to the beams 15 onoach'side near their edges, and to their (nit-standing flanges issecured comprossion-plate 21, which passes beneath the lower flanges ol'the ccntcrsills. Instead of the usual tension-plate I employ one or moretension-rods 22, passing over and resting upon the upstanding struts 13and supporting at their outer ends the bodybolster beams and side sills.For this purpose I employ angular caps or anchors 23, each of whichcomprises a horizontal portion 25, extending beneath the body-bolsterbeam and the ilanges ol the side sill, while the upright portion 24overlaps the vertical flange oi the side sill and tends on each side ofthe side stake 18, as shown in Fig. 1. Each angular cap or anchor 23 hasthe boss 26,

ds of tension-rods nuts on the ends of the rods holding the partstogether, the rods resting on struts 13. On the accompanying drawings Ihave illustrated two such tension-rods; but it is ap parent that anynumber oi the same may be used, as conditions require.

As a support or strut for the tom of the hopper-car plate 28, riveted tothe cured at its outer ends to the side stakes by means of the angles30. The inclined lower edges of this plate are supplied with integralcompression-llanges 29, is shown in Fig. 3. To connect this bellied.plate, which constitutes a strut or support for the bottomof the car, tothe latter, I provide anglebar 32, which is riveted to the plate andalso to the bottom of the car-body. I have shown and through which passthe on 9) sloping hot- I provide the bellied spaced lugs 14 and se- ICCdescribed this portion of the invention as applied to a hopper-car withan inclined bottom; but it is obvious that the invention may be used inconnection with car-bodies other than that shown and described.

Since the spacer, struts, and lugs are integral, it is evident that theunderi'rame of the car, including the body-bolster, can be quicklyassembled, owing to the small number of parts, and it will also beapparent that the tension-rods 22 may be readily put in place or removedby merely unscrewing the nuts at their outer ends, no cutting of rivetsbeing required. It will also be obvious that my improved means forsupporting the carbody above the body-bolster involves a very simpleconstruction, which nevertheless provides suflicient strength with aminimum of weight. Instead of making plates 15 and 28 integral, as hasbeen usual, I make the latter bellied in shape and separate from thebolster-beams, in this way saving somewhat in the weight of the partsand at the same time constructing plate 28 of a shape to effectuallywithstand the load or strain put upon it.

Obvious and minor mechanical changes which will suggest themselves tothose skilled in the art will fall within the substance of my inventionas defined. in the appended claims.

This patent is intended to embrace only so much of the disclosure madeherein as is covered by the claims.

I claim 1. In a car frame, the combination of spaced center sills, anintegral strut and spacer for said sills, body-bolster beams secured tosaid sills, a tension rod or rods resting on said strut, and anchorsunder the outer ends ol" said bolster-beams fastened to .the ends of thetension rod or rods, substantially as described.

2. In a railway-car, the combination of a car-body spaced center sills,a spacer for said sills, and a car-body-supporting plate fastened tosaid spacer and to said car-body, substantially as described.
